AstraZeneca and Merck’s LYNPARZA, When Added
to Standard-of-Care Bevacizumab, Significantly Reduced the Risk of
Disease Progression or Death in Women Who Responded to
Platinum-Based Chemotherapy
AstraZeneca and Merck (NYSE: MRK), known as MSD outside the
United States and Canada, today announced positive results from the
Phase 3 PAOLA-1 trial in women with advanced ovarian cancer. The
trial, in the first-line maintenance setting, compared LYNPARZA
added to standard-of-care bevacizumab versus bevacizumab alone in
women with or without BRCA-gene mutations.
The trial met its primary endpoint in the intent-to-treat (ITT)*
population with a statistically-significant and
clinically-meaningful improvement in progression-free survival
(PFS) for women taking LYNPARZA plus bevacizumab, versus those
taking bevacizumab alone, as a first-line maintenance treatment
following response to standard first-line platinum-based
chemotherapy and bevacizumab. The results, including biomarker
sub-group analyses, will be presented at a forthcoming medical
meeting. The safety and tolerability profiles observed in PAOLA-1
were generally consistent with those known for each medicine.
PAOLA-1 is the second positive Phase 3 trial with LYNPARZA in
first-line advanced ovarian cancer.
Dr. José Baselga, executive vice president, Oncology R&D,
AstraZeneca, said, “The positive results from the PAOLA-1 trial
demonstrate a clear potential benefit of adding LYNPARZA to the
standard treatment bevacizumab for women with advanced ovarian
cancer. Following positive results from the SOLO-1 trial for women
with a BRCA gene mutation, the PAOLA-1 trial marks yet another
positive Phase 3 trial for LYNPARZA as a first-line maintenance
treatment for women with advanced ovarian cancer. We look forward
to discussing the results with global health authorities as soon as
possible.”
Dr. Roy Baynes, senior vice president and head of global
clinical development, chief medical officer, Merck Research
Laboratories, said, “The Phase 3 PAOLA-1 trial demonstrates Merck
and AstraZeneca’s continued commitment to improving clinical
outcomes for women with advanced ovarian cancer. In this
co-operative group trial sponsored by ARCAGY Research, maintenance
treatment with LYNPARZA when added to a standard-of-care treatment
was evaluated in an environment representative of real clinical
practice. By studying LYNPARZA in this broader patient population,
we have learned more about how it may help even more patients with
advanced ovarian cancer in the future.”
Eric Pujade-Lauraine, Medical Director of ARCAGY Research, said:
“The PAOLA-1 trial is a positive example of the strength and
promise of academia-industry collaboration in advancing science and
new treatment options for patients. We greatly appreciate the
commitment of AstraZeneca and Merck in working with academic
cooperative groups in ENGOT and look forward to sharing the full
PAOLA-1 results at a forthcoming medical meeting.”
PAOLA-1 is an ENGOT (European Network for Gynecological Trial)
trial, sponsored by ARCAGY Research (Association de Recherche sur
les CAancers dont Gynecologiques) on behalf of GINECO (Groupe
d’Investigateurs National des Etudes des Cancers Ovariens et du
sein). ARCAGY-GINECO is an academic group specializing in clinical
and translational research in women’s cancers and a member of the
GCIG (Gynecologic Cancer InterGroup).
About PAOLA-1
PAOLA-1 is a randomized, double-blind Phase 3 trial evaluating
the efficacy and safety of LYNPARZA when added to standard-of-care
bevacizumab versus bevacizumab alone, as first-line maintenance
treatment for advanced FIGO Stage IIIB-IV high grade serous or
endometroid ovarian, fallopian tube, or peritoneal cancer patients
who had a complete or partial response to first-line treatment with
platinum-based chemotherapy and bevacizumab. *The ITT
(intent-to-treat) population refers to all patients enrolled in the
trial.
IMPORTANT SAFETY INFORMATION
CONTRAINDICATIONS
There are no contraindications for LYNPARZA.
WARNINGS AND PRECAUTIONS
Myelodysplastic Syndrome/Acute Myeloid Leukemia
(MDS/AML): Occurred in <1.5% of patients exposed to LYNPARZA
monotherapy, and the majority of events had a fatal outcome. The
duration of therapy in patients who developed secondary MDS/AML
varied from <6 months to >2 years. All of these patients had
previous chemotherapy with platinum agents and/or other
DNA-damaging agents, including radiotherapy, and some also had a
history of more than one primary malignancy or of bone marrow
dysplasia.
Do not start LYNPARZA until patients have recovered from
hematological toxicity caused by previous chemotherapy (≤Grade 1).
Monitor complete blood count for cytopenia at baseline and monthly
thereafter for clinically significant changes during treatment. For
prolonged hematological toxicities, interrupt LYNPARZA and monitor
blood count weekly until recovery.
If the levels have not recovered to Grade 1 or less after 4
weeks, refer the patient to a hematologist for further
investigations, including bone marrow analysis and blood sample for
cytogenetics. Discontinue LYNPARZA if MDS/AML is confirmed.
Pneumonitis: Occurred in <1% of patients exposed to
LYNPARZA, and some cases were fatal. If patients present with new
or worsening respiratory symptoms such as dyspnea, cough, and
fever, or a radiological abnormality occurs, interrupt LYNPARZA
treatment and initiate prompt investigation. Discontinue LYNPARZA
if pneumonitis is confirmed and treat patient appropriately.
Embryo-Fetal Toxicity: Based on its mechanism of action
and findings in animals, LYNPARZA can cause fetal harm. A pregnancy
test is recommended for females of reproductive potential prior to
initiating treatment.
Females
Advise females of reproductive potential of the potential risk
to a fetus and to use effective contraception during treatment and
for 6 months following the last dose.
Males
Advise male patients with female partners of reproductive
potential or who are pregnant to use effective contraception during
treatment and for 3 months following the last dose of LYNPARZA and
to not donate sperm during this time.

DRUG INTERACTIONS
Anticancer Agents: Clinical studies of LYNPARZA in
combination with other myelosuppressive anticancer agents,
including DNA-damaging agents, indicate a potentiation and
prolongation of myelosuppressive toxicity.
CYP3A Inhibitors: Avoid concomitant use of strong or
moderate CYP3A inhibitors. If a strong or moderate CYP3A inhibitor
must be co-administered, reduce the dose of LYNPARZA. Advise
patients to avoid grapefruit, grapefruit juice, Seville oranges,
and Seville orange juice during LYNPARZA treatment.
CYP3A Inducers: Avoid concomitant use of strong or
moderate CYP3A inducers when using LYNPARZA. If a moderate inducer
cannot be avoided, there is a potential for decreased efficacy of
LYNPARZA.
USE IN SPECIFIC POPULATIONS
Lactation: No data are available regarding the presence
of olaparib in human milk, its effects on the breastfed infant or
on milk production. Because of the potential for serious adverse
reactions in the breastfed infant, advise a lactating woman not to
breastfeed during treatment with LYNPARZA and for 1 month after
receiving the final dose.
Pediatric Use: The safety and efficacy of LYNPARZA have
not been established in pediatric patients.
Hepatic Impairment: No adjustment to the starting dose is
required in patients with mild or moderate hepatic impairment
(Child-Pugh classification A and B). There are no data in patients
with severe hepatic impairment (Child-Pugh classification C).
Renal Impairment: No adjustment to the starting dose is
necessary in patients with mild renal impairment (CLcr=51-80
mL/min), but patients should be monitored closely for toxicity. In
patients with moderate renal impairment (CLcr=31-50 mL/min), reduce
the dose to 200 mg twice daily. There are no data in patients with
severe renal impairment or end-stage renal disease (CLcr ≤30
mL/min).

About LYNPARZA® (olaparib)
LYNPARZA is a first-in-class PARP inhibitor and the first
targeted treatment to potentially exploit DNA damage response (DDR)
pathway deficiencies, such as BRCA mutations, to preferentially
kill cancer cells. Inhibition of PARP with LYNPARZA leads to the
trapping of PARP bound to DNA single-strand breaks, stalling of
replication forks, their collapse and the generation of DNA
double-strand breaks and cancer cell death. LYNPARZA is being
tested in a range of tumor types with defects and dependencies in
the DDR.
LYNPARZA, which is being jointly developed and commercialized by
AstraZeneca and Merck, has a broad and advanced clinical trial
development program, and AstraZeneca and Merck are working together
to understand how it may affect multiple PARP-dependent tumors as a
monotherapy and in combination across multiple cancer types.
About Ovarian Cancer
Ovarian cancer the eighth most common cause of death from cancer
in women worldwide, with a five-year survival rate of approximately
19%. In 2018, there were nearly 300,000 new cases diagnosed and
around 185,000 deaths. For newly-diagnosed advanced ovarian cancer,
the primary aim of treatment is to delay progression of the disease
for as long as possible and maintain the patient’s quality of life
with the intent of achieving complete remission or cure.
